Schema for Representing Java(tm) Objects in an LDAP Directory

RFC 2713                Schema for Java Objects             October 1999


   javaClassNames is a multivalued attribute that is used to store the
   fully qualified names of the object's Java classes and interfaces
   (for example, "java.lang.Byte"). Like all multivalued attributes, the
   javaClassNames attribute's values are unordered and so no one value
   is more "distinguished" than the others. This attribute is intended
   for storing an object's class and interface names and those of its
   ancestor classes and interfaces, although the list of values does not
   have to be complete.  If the javaClassNames attribute is present, it
   should include the value of javaClassName.

   For example, suppose an object is stored in the directory with a
   javaClassName attribute of "java.io.FilePermission", and a
   javaClassNames attribute of {"java.security.Permission",
   "java.io.FilePermission", "java.security.Guard",
   "java.io.Serializable"}. An application searching a directory for
   Java objects might use javaClassName to produce a summary of the
   names and types of Java objects in that directory.  Another
   application might use the javaClassNames attribute to find, for
   example, all java.security.Permission objects.

   javaCodebase is a multivalued attribute that is used to store the
   location(s) of the object's class definition.  javaDoc is used to
   store a pointer (URL) to the Java documentation for the class.
   description is used to store a textual description of a Java object
   and is defined in [v3Schema]. The definitions of these attributes are
   presented in Section 3.

2.2 Serialized Objects

   To "serialize" an object means to convert its state into a byte
   stream in such a way that the byte stream can be converted back into
   a copy of the object.  A Java object is "serializable" if its class
   or any of its superclasses implements either the java.io.Serializable
   interface or its subinterface java.io.Externalizable.
   "Deserialization" is the process of converting the serialized form of
   an object back into a copy of the object.  When an object is
   serialized, the entire tree of objects rooted at the object is also
   serialized. When it is deserialized, the tree is reconstructed. For
   example, suppose a serializable Book object contains (a serializable
   field of) an array of Page objects.  When a Book object is
   serialized, so is the array of Page objects.

   The Java platform specifies a default algorithm by which serializable
   objects are serialized. A Java class can also override this default
   serialization with its own algorithm.  [Serial] describes object
   serialization in detail.
